The present invention relates to artificial leather, a manufacturing method therefor, and a ventilation seat and vehicle using the same. The artificial leather according to the present invention comprises: a non-woven fabric; an air permeable hole formed inside the non-woven fabric penetrating from one surface of the non-woven fabric to the other surface thereof which is opposite to the one surface; and nappings formed on at least one surface of the non-woven fabric. The exposure ratio of the air permeable hole according to equation 1 is higher than or equal to 0.1% and lower than or equal to 40%, and when viewed on the surface of the non-woven fabric on which the nappings are formed, the average length of nappings, which covers the air permeable hole, is higher than or equal to 100 μm and lower than or equal to 400 μm.
